MACHINE FOR TREATING PEAT.

SPECIFICATION forming part of Letters Patent No. 658,281, datedSeptember 18, 1960,

Application filed March 18, 1899.

T0 at whom it may concern/.-

Be it known that I, ADOLF ROM, a citizen of Norway, residing at Lian,near Ohristiania, Norway, have invented Improvements in Machines forTreating Peat, of which the following is a specification.

According to this invention peat fibers are extracted from the peat bycarrying the latter after it has been suitably reduced between twocard-like bands or belts running in the same direction, but with unequalvelocity, which belts are provided with studs or knives, the knives onthe band that has the greatest velocity receiving the fibers, which areafterward taken off the knives by means of a fan or some other suitableapparatus.

A preferred form for the invention is shown in the accompanyingdrawings.

A is a stand with bearings for two pairs of drums B B O O for bands Fand G, provided, respectively, with knives D and spikes E. In themachine shown each band consists of two belts, strings, chains, 850., H,placed at some distance from each other and between which are placedtransversal plates I, in which the knives and the spikes are fastened.The bottom band is supported by a suitable guide K, which faces theupper band. As shown in the drawings, the bands I and G are lying soclose to each other that the knives on the former pass between thespikes in the latter, whereby the knives on the band F, which moves at agreater speed than the band G, will comb the fibers out of the peat,which latter is retained by the spikes E. It is advisable to give thespikes on the band G an elliptic section, whereas the knives on theother band may on the front side he provided with a comparatively-sharpedge. The section of the knives is lenticu'lar in order to facilitatethe release of the combed fibers from the knives. The section form ofthe spikes and knives is shown in Figure 2, which is a Serial No.709,635 (No model.)

horizontal section through Fig. 1, taken be tween ,the bands. In theexample shown the release of the fibers from the knives is effected bymeans of a fan L, placed near the knife-band F at the back end of themachine and revolving in the direction indicated by the arrow and whichis given a greater peripheral speed than the band. The blades of the fanmay, if desired, be cut comb-like at the outer edge, so as to form teeththat from behind fetch between the knives and the fibers attaching tosame in the space formed between these on account of the knives beingmade thinner at the back edge than in the middle. Instead of the fan asimilarly-arranged brush may be used. The peat is fed into the machineat M insuitable reduced form.

As a machine of the kind specified works perfectly automatically, it mayWithout the least annoyance or hindrance to the production ofpeat-litter be placed between the machines employed for this purpose.

I claim In a machine of the class described, the combination of twoendless belts, one of said belts having teeth of lenticular form insection blunted at their rear edge, and the other, teeth of ellipsoidalform in section working between said lenticular teeth, the teeth on bothbelts set to leave considerable space between them, and means fordriving the cooperative portions of said belts in one and the samedirection, the upper belt traveling at a greater speed than the lowerone, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ADOLF ROM.
